I don't go by numbers, I go by feel. I want to "feel" the trailer starting to pull against me when I brake easy to mid. mine is set on 8. Also in the new Ford I use the exhaust brake and when used properly along with Tow Haul mode it will all but bring you to a complete stop when existing the interstate.

I press the brakes mid to hard for about 3 seconds after coming off cruise, that will engage exhaust brake and start an aggressive down shifting and then I won't touch brakes again until just before stop sign at top of exit ramp because exhaust brake and the truck downshifting (not manually) has brought me to around 2-5 mph.
